Indole and Derivatives Modulate Biofilm Formation and Antibiotic Tolerance of .

Intercellular communication is a crucial process for the multicellular community in both prokaryotes and eukaryotes. Indole has been recognized as a new member of the signal molecules which enables the regulated control of various bacterial phenotypes. To elucidate the inter-species relationship among enteric microorganisms via indole signaling, (KP) culture was treated with indole solution and examined for the pathogenicity by using various phenotypic tests.
